After tinkering with it a bit, a couple of my original guesses as to
the underlying problem were clearly wrong. I'm moving house next week,
so it'll be a while before I get to look at it in detail, but I added
Mark Shannon to the issue's nosy list. He's been working on a few
patches lately to clean up generator related state handling in
general, so he may have some insight into this.

Cheers,
Nick.
